My tv is about 3-4 years old. What is causing the picture to go dark. I’ve checked the brightness and have reset everything. Still not bright.
@deek72 could be a bad panel, bad power board/inverter or bad LED backlight array. It will depend on how dark it gets. Post some images of what you see with your question. Use this guide for that. Remove the back of your TV after you unplug it and take some pistures of the boards on the inside of your TV as well. Let us know what the model is.
The most cause for dark screen is defective Led’s inside the panel Some of the leds are failing and causing the screen to look dark on one side or entirely. You will need to replace the led strips in the panel to resolve the issue. Shopjimmy.com has a lot of backlight stripes for purchase, This is a major repair and will take time and patience to replace them. They also have a video on how to replace Backlight strips. Also check the V+ And V- voltages going to the panels leds

I have a tcl roku tv that just went dark. But when you try to turn it off there is a little bit brightness but not too much. I made my way around to the brightness and it didn’t do a thing. It powers on and off okay. Do you think it’s the led? Is it worth to fix it?
The issue is most likely the back lights to the tv have blown If that doesn’t fix it then it is a motherboard problem
